1 Claim.

This invention relates to smoking pipes and has for an object to providea pipe which will produce a dry smoke.

Another object of the invention is to provide in a smoking pipe, meanswhereby the smoke will be properly cooled before reaching the mouth ofits user.

A further object of the invention is to provide a smoking pipe, thesmoke passage through the stem of which gradually increases in diameterfrom the bowl to the mouthpiece thereof.

Other features and advantages will become more readily apparent from thefollowing description and the accompanying illustrative drawing inwhich:

The gure is a longitudinal sectional elevational view of my improvedpipe.

Same reference characters indicate same parts in the drawing andspecification, and I indicates one form of the invention.

In the figure, I2 indicates a smoking pipe bowl having a stem sectionI3, the smoke channel I4, of which tapers in diameter from thecomparatively very small port I 5 at one side of the bottom of the bowl,to the end I 6 of member I3. To said end I 3, is connected a detachablestem or mouthpiece section I1, having a tapering passage I3, thediameter of which at its juncture I9 with the smoke channel I4 is thesame as the outer terminal diameter 20 of said smoke channel in sectionI3, and which gradually increases in diameter to its outlet 25 at theouter extremity of the mouthpiece I'I.

It will thus be observed that the smoking pipe embodying the inventionhas a straight-walled smoke passage which gradually and continuouslyincreases in diameter or cross-sectional area from a small opening inone side of the bowl adjacent the bottom thereof to the outer extremityof the mouthpiece, whereby free and rapid movement of smoke and moisturefrom the bowl to the outlet 25 of the mouthpiece is insured and settlingdown or condensation of moisture in the smoke passage is prevented.

I have proved through my comparative experi- Fort Lee, N. J.

ments with the above described pipe and those having straight boresthrough the pipe stem that I have invented a smoking pipe which gives adryer, cooler and in every way a more pleasant smoke than those of theusual construction.

It is thought that persons skilled in the' art to which the inventionrelates will be able to obtain a clear understanding of the inventionafter considering the description in connection with the drawing.Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in shape, size and rearrangement of details and parts suchas come within the purview of the invention claimed may be resorted to,in actual practice, if desired.

Having now described my invention that which I claim as new and desireto procure by Letters Patent is:

A smoking pipe comprising a bowl, a stem and a mouthpiece, said stem andmouthpiece comprising a smoke passage starting at the tobacco holdingcavity of the bowl adjacent the bottom thereof and terminating at thefree end of the mouthpiece; said passage in entirety being uniformlytapered in at least one longitudinal section from a smallcross-sectional area at the bowl end to a larger cross-sectional area atthe free end of the mouthpiece.
